Many archaeological materials have been found in Thailand, such as ceramics, pottery, glass and amulets, etc. In this work, the particle-induced X-ray emission (PIXE) method based on the 2 MeV proton beam of Chiang Mai University was used to analyze the atomic composition of ancient glass beads, decorative glass Thai amulets. It has been demonstrated that PIXE, non-destructive and without any sampling method, has been used as an efficient technique to analyze archaeological objects in a few minutes, in order to understand their characteristics and how they were produced in antiquity. Keywords: PIXE, ceramic ancient, ancient glass bead, decorative glass, amulet1. INTRODUCTIONHistorical glasses have been used as ornaments and decorations in Thailand for several hundred years, as demonstrated by archaeological evidence such as glass beads collected from different regions of the country. Decorative glass such as antique glass and antique enamel are generally found as architectural components in ancient palaces and Buddhist objects. Archaeological dating indicates that ancient glass beads were made more than 1300 years ago, while ancient glass and enamels were more than 600 years old [1, 2]. Ancient Thai Glass (ATG) samples a type of decorative glass, by some At the Ayutthaya Buddhist World Heritage Site in central Thailand, small broken pieces were found on the ground. They were available in different colors, such as red, green, blue and amber. The glass samples were mostly monochrome and flat with a thickness of approximately 0.2 mm. Previous work, ATG blue, green and colorless, had already been analyzed and shown that it was lead-based glass, and Co and Cu were the dyes for the blue and green...... center of paper .... ...decorative glass and amulets, as a branch of archaeology, have focused on defining the data and the area of ​​production. ACKNOWLEDGMENTS Financial support was partly provided by the Faculty of Science, Kasetsart University, Thailand. The works were developed within the scope of the activities of the Glass and Glass Products Research and Development Laboratory of the Institute of Scientific and Technological Research of Chiang Mai University (Chiang Mai, Thailand) and the Plasma Physics Facility and of the rays at the Faculty of Science of Chiang Mai University, the Service Center for Science and Technology at the Faculty of Science of Chiang Mai University. The Royal Household Office, the Faculty of Archeology of Silpakorn University and Air Vice Marshal Chatpisut Kamchareonpassorn were thanked for the samples of ancient Thai glass, ancient glass beads and Phra Somdej Wat Rakhang respectively.
